i INVENTOR age/@e @wif/5&5@ BY 'a L /w ATTORN EY S Patented Aug. 20, 1946 SEPARABLE MEMBERS Eugene Morehouse, Providence, R. I., assigner to B. A. Ballou & Co., Inc., a corporation of Rhode Island Application September 13, 194,3, SerialNo. 502,100 A I This invention relates to separable members such for instance as separable culi?A buttons or the like and is an improvement upon Patent No, 1,595,055, dated August 3, 1926, owned by the same assignee as the assignee of this application. l

In the patent above-referred to the resilient means for retaining the button members in engagement consists of two bulging wire portions which engage back of the shoulder of a stud. All of the strain is carried upon these two wire bulging portions and these wires must be made of a suicient diameter to withstand the strain impressed upon them which may require a spring heavier than that otherwise which would be used.

One of the objects of this invention is to provide separable members which may be made with lighter weight resilient Wire and yet provide a stronger holding action between the parts.

`Another of the objects of this invention is to increase the holding power between the separable members by increasing the number of portions upon which strain occurs which will permit of the wire which forms the support to be made of lighter weight material and yet provide a stronger holding of the two separable parts one with the other.

Another object of this invention is t provide a construction in which the spring or resilient means may be held in place in a very simple manner affording a quick and simple assembling operation.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

' 4 claims. (c1. 24-109) The stud of one member of the separable butl ton of the above patent at its holding shoulder is provided with opposite pairs of ribs which serve to flex the holding spring means whenrelease is desired and .I utilize the spaces betweeneach of these vribs .to insert additional holding means so'that instead of two'sprin'g wire projections alone serving to hold the members together I provide a greater support between the members than was heretofore found in the patent above referred to.

With reference to the drawing I have shown this invention as applicable to separable cuff buttons in which I0 designates the stud member and II designates generally the socket member. The stud member is provided with heads I2 and I3 with a cylindrical post or stud I4 projecting beyond the inner head I 3. This stud I4 is notched as at I8 to provide spaced shoulders I5 and I6 rthe latter between this notched portion and the free end portion of the stud. Four ribs I1 are left between the notches and arranged in opposite pairs, as shown more clearly in Figs. 3 and 4.

The socket member II also consists of a pair of inner and outer heads 20 and 2| leaving a spool-like portion 22 having a recess 23 within for the reception of the stud I4 as shown in Fig. 1. The head 2u is formed by outwardly aring the spool portion as atv 24 with an outer wall 25 rolled into engagement therewith as at 26 which is provided with a central opening 21 for the reception of the stud. An inner spring confining wall 28 having downwardly rolled edges 29 is held in position by the inwardly extending portion 30 of the enlarged end 24 and is also provided with an opening 3| through which the stud I4 may pass. Between these walls 25 and 28 I have provided a spring or resilient means 33 in the shape best shown in Figs. 3 to 4, while projections 34 are raised on one of the walls so as to hold the right angularly extending junction portions of the spring in position. An additional raised portion 35 assists in holding the spring in centralized position and also may serve as a stop to limit the inward movement of the engaging arm portions of the spring when desired.

The spring 33 is generally of a U-shape with legs 36 and a bridging portion 31. The legs 36 are turned inwardly as at 38 to provide arms 39 which are 'so bent as to provide inwardly extending protuberances 4I! and 4I with an outward junction point 42 between. The arc of the portions 40 and 4I is such as to nicely fit recesses I8 in the stud andbe positioned between the ribs II thereof.

by al1 of its shoulder portions and yet for release it is merely necessary to turn the stud with reference to the socket through substantially 45 degrees into the position shown in Fig. 4 which will flex outwardly all of the holding portions 40, 4| of the arms 39 and permit the stud I4 to be withdrawn from the socket. A maximum holding is thus obtained."

In some'eases-instead of utilizing' a wall such as shown at 28 in Fig. 2, the Wall 25 as shown in Fig. '1 may be turned inwardly to provide a tubu-v lar portion 45 which may be provided with two' slots 46 as shown in Fig. 6 through which both projections 40 and 4| may extend or'the slots may be four in number as' shown at 4T and 48 in Fig. 8, leaving a wall portion of the tubular extension 45 as at 49 between ythe slots 4l .and 48. These latter two forms provide somewhat more control for the spring and may serve to limit the inward extent of the bulging `portions which engage `the shoulders for `holding ,the same.

A1. separable means comprising a cylindrical .stud member having a plurality of :notches equally singularly disposedabout its axis and providing shoulders in substantially a plane at right angles to said axis spaced from one end thereof, and a aration 'ofsaid memberss'aid protuberances being at least three in number, and said notches being provided in a number which is an integral multiple of the number of protuberances` 2. Separable means as set forth in claim l wherein ,said protuberances are formed by bendingna single piece of wire and disposing the same in substantially a single plane at right angles to said axis.

.3. Separable means as set forth in claim l wherein means are provided to limit the movement of said protuberances toward each other when said stud is withdrawn from said opening.

4. separable means as set forth in claim 1 wherein said protuberances andl notches are four in number. Y
